Upgrading Vertica on Kubernetes

The operator automates Vertica server version upgrades for a custom resource (CR).

Online upgrade

The current online upgrade policy has been renamed to ReadOnlyOnline, and we now have a new approach for online upgrades. This updated mechanism ensures the database remains active and capable of continuous writes through replication. Additionally, we implemented session transfer to further improve the upgrade experience.
